Check your miner status tab, the freq now should be 393 and the temperature should be 50 or lower, higher temperature running for long time might damage the chips, add extra fan if you can, push and pull air same direction.

This work great for me, and I did it multiple times testing and the end result I got 8 s1 miner up and running with 200gh/s. My next todo would be to integrate the fan to the blade fan power connector and make it spin 100% instead of being controlled by the blade or controller.

It is definitely worth it to overclock it. Unless you pay 50 cent per kilowatts power usage per hour. I’m currently paying 12 to 13 cent per kilowatts. the 20GH/s help. Total of 1.6TH/s for my 8 S1 miner, which I will be putting up on ebay for sell soon, like in a couple weeks, then use the money to buy another miner, better.
